Description

Technical Field

[0001] The invention relates to the technical field of transformer welding, in particular to a transformer cooling oil tank edge welding device. Background Art

[0002] In the field of power equipment manufacturing, transformers are key components, and their performance and stability are of vital importance. The transformer cooling oil tank is an important part of the transformer heat dissipation. Its structural design and manufacturing process directly affect the operating efficiency and service life of the transformer. Figure 1 As shown, the edge structure of a traditional transformer cooling oil tank is usually composed of four angle steels, including two long angle steels with notches at both ends and two short angle steels. Fixing holes for subsequent reinforcement connections are opened on the long angle steels and the short angle steels. These angle steels are connected together through a precise welding process to form a stable and effective cooling oil tank frame.

[0003] In the existing production process, this welding step mainly relies on manual operation. Specifically, the operator first needs to place four angle steels on the welding table one by one according to specific angles and positions, and then use limit clamps to position and fix the angle steels. This operation needs to be repeated many times a day, which is labor-intensive.

[0004] More importantly, since the entire welding process is almost entirely done manually, the welding quality is closely related to the operator's technical level, experience and concentration. This high degree of manual dependence makes it difficult to uniformly control the welding quality. There may be significant differences between welds completed by different batches or different workers, and the welding quality varies. This quality inconsistency not only affects the overall structural strength of the cooling oil tank, but may also have an adverse effect on the heat dissipation performance of the transformer, thereby shortening the transformer's service life or increasing the risk of failure.

[0005] In view of the above problems, the prior art urgently needs a device that can automatically and accurately complete the welding of the edge angle steel of the transformer cooling oil tank to reduce labor intensity and ensure the consistency and reliability of welding quality.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] See also Figure 1-Figure 14The present invention provides a technical solution: a transformer cooling oil tank edge welding device, comprising a workbench 1, a support frame 2, a first conveyor 3, and a second conveyor 4. The workbench 1 and the support frame 2 are in adjacent positions, and a vertical plate 11 is fixed on the workbench 1, and a horizontal plate 12 is fixed on the side of the vertical plate 11 close to the support frame 2. The first conveyor 3 and the second conveyor 4 convey the long angle steel and the short angle steel respectively, and the discharge ports of the two are located directly above the support frame 2, and the conveying is alternately performed, so that the device can adjust the angle steel to the different states required by the four sides of the box edge in sequence later, and also includes:

[0043] The first square tube 5 is installed on the top of the support frame 2 and passes through the support frame 2, and its side length is equal to the side length of the angle steel. One end of the first square tube 5 away from the support frame 2 is connected to a conical upper hopper 51, and a vibrator 52 is installed on the outer wall of the conical upper hopper 51. The wide-mouth end of the conical upper hopper 51 is located directly below the discharge ports of the first conveyor 3 and the second conveyor 4;

[0044] The adjustment mechanism 6 is installed on the support frame 2 and connected to the first square tube 5. The adjustment mechanism 6 identifies the type of angle steel in the first square tube 5, adjusts the longitudinal height of the corresponding angle steel, and drives the angle steel to rotate about the axis of the first square tube 5, so that the side of the angle steel with the fixing hole is located on a plane parallel to the vertical plate 11;

[0045] Angle adaptation mechanism 7, which is mounted on the horizontal plate 12 and connected to the adjustment mechanism 6. The angle adaptation mechanism 7 rotates the angle steel adjusted by the adjustment mechanism 6 to an angle suitable for welding according to the type and quantity of the angle steel identified by the adjustment mechanism 6;

[0046] A double-axis translation mechanism 8, which is installed on the vertical plate 11 and connected to the angle adaptation mechanism 7. The double-axis translation mechanism 8 drives the angle steel to perform horizontal translation in the horizontal plate 12 or to perform horizontal or vertical translation on the vertical plate 11 through the angle adaptation mechanism 7;

[0047] The clamping mechanism 9 is installed on the vertical plate 11, and the clamping mechanism 9 clamps and positions the angle steels on the vertical plate 11 respectively;

[0048] The welding mechanism 10 is installed on the vertical plate 11 and is used for welding the connection between the long angle steel and the short angle steel.

[0049] The cone angle of the conical upper hopper 51 is 25°-35°. After the angle steel enters the conical upper hopper 51, the conical guidance within this angle range can prevent the conical upper hopper 51 from being too long while driving the angle steel to be as close to a vertical state as possible. It can pass through the conical upper hopper 51 into the first square tube 5 at a faster speed, and the vibrator 52 drives the conical upper hopper 51 to shake, which can prevent the angle steel from getting stuck in the conical upper hopper 51.

[0050] The adjusting mechanism 6 comprises a second square tube 61 sleeved on the first square tube 5, a fixing plate 62 is installed at one end of the second square tube 61 close to the top of the support frame 2, a first electric push rod 63 is installed on the inner side of the top of the support frame 2, one end of the push rod of the first electric push rod 63 is connected to the fixing plate 62, a circular ring 64 is fixed at the other end of the second square tube 61, a limiting hole 65 is arranged on the inner wall of the circular ring 64, and there are several limiting holes 65, a swivel 66 is rotatably connected in the circular ring 64, a third rectangular tube 67 passes through the center of the swivel 66, and the side length of the third rectangular tube 67 is equal to that of the first square tube 5, a cylindrical groove 68 is arranged on the outer wall of the circular ring 64, and the number of the cylindrical groove 68 and the limiting hole 65 is the same, a spring 69 is arranged in the cylindrical groove 68, and the end of the spring 69 away from the cylindrical groove 68 is connected to the limiting ball 610, and the adjusting mechanism 6 also comprises an auxiliary part 611 installed on the bottom surface of the support frame 2.

[0051] The auxiliary part 611 includes a second electric push rod 6111 installed on the support frame 2, the second electric push rod 6111 is located directly below the third rectangular tube 67, a servo motor 6112 is installed on the top of the second electric push rod 6111, a support plate 6113 is installed on the output shaft of the servo motor 6112, a square block 6114 is installed on the support plate 6113, the side length of the square block 6114 is equal to the side length of the inner wall of the angle steel, a support rod 6115 is installed on the square block 6114, and the support rod 6115 is respectively installed with the third rectangular tube 67. A sensor 6116 and a second sensor 6117, the first sensor 6116 is located above the second sensor 6117, and four sensor heads are provided on the first sensor 6116 and the second sensor 6117, and are distributed in a cross shape, the distance between the first sensor 6116 and the support plate 6113 is equal to the distance from one end of the long angle steel to the second fixing hole on the corresponding side thereof, and the distance between the second sensor 6117 and the support plate 6113 is equal to the distance from one end of the short angle steel to the first fixing hole on the corresponding side thereof.

[0052] Take the front view of the vertical plate 11 as a reference, and the first conveyor 3 first puts the first long angle steel into the example:

[0053] Under the action of gravity, the long angle steel slides downward through the first square tube 5, and finally the end close to the ground contacts the support plate 6113. At the same time, the two inner walls of the long angle steel are respectively attached to two sides of the square block 6114. The first sensor 6116 and the second sensor 6117 can be infrared sensors or laser sensors, which are prior arts and are used to detect whether there is an object blocking them. Since the distances from one end of the long angle steel and the short angle steel to their respective corresponding fixing holes are different, when a single one of the four sensing heads of the first sensor 6116 is blocked and two of the four sensing heads of the second sensor 6117 are blocked, it can be known at this time that the product being detected is the long angle steel. On the contrary, when two of the four sensing heads of the first sensor 6116 are blocked and one of the four sensing heads of the second sensor 6117 is blocked, it is the short angle steel; after confirmation, the second electric push rod 6111 is activated, and the long angle steel is driven by the servo motor 6112 and the support plate 6113 to adjust the height, so that the midpoint of the long angle steel is on the same horizontal plane as the center point during welding. Subsequently, the first electric push rod 63 is activated, and the second square tube 61 is driven by the fixing plate 62 to continuously overlap with the first square tube 5. The second square tube 61 synchronously drives the third square tube 67 to rise through the circular ring 64 and the swivel ring 66. Since the lengths of the long angle steel and the short angle steel are fixed, by combining the extension or shortening distance of the first electric push rod 63 with the extension or shortening distance of the second electric push rod 6111, the end of the long angle steel close to the first square tube 5 can be separated from the first square tube 5 and the second square tube 61 and enter the third square tube 67. Subsequently, the servo motor 6112 is activated, and the long angle steel is driven by the square block 6114 to rotate, so that the surface with the fixing hole is opposite to the plane where the vertical plate 11 is located. The operation of the short angle steel is the same.

[0054] The angle adaptation mechanism 7 includes a first chute 71 opened on the cross plate 12. A square sliding cylinder 72 is slidably arranged in the first chute 71. A micro stepping motor 73 is arranged in the square sliding cylinder 72. An adsorption frame 74 is installed on the output shaft of the micro stepping motor 73. The longitudinal midpoint of the adsorption frame 74 is on the same horizontal plane as the center point during the welding of the box edge. The adsorption frame 74 is in a "C" shape, and first electromagnets 75 are oppositely installed on the inner walls of the adsorption frame 74.

[0055] Since the state of the angle steel entering the first square tube 5 through the conical hopper 51 is random, the surface of the angle steel with the fixing hole is always opposite to the plane where the vertical plate 11 is located after being adjusted by the adjustment mechanism 6. The surface without the fixing hole may appear on the left or on the right in two cases. The state of the angle steel can be confirmed according to the first sensor 6116 and the second sensor 6117. Taking the front view of the vertical plate 11 as a reference, if the long angle steel that is above during the welding process is placed first:

[0056] If the side without the fixing hole appears on the left, the first electromagnet 75 is turned on to adsorb the long angle steel, and the micro-stepping motor 73 drives the adsorption frame 74 to rotate 90° counterclockwise;

[0057] If the side without the fixing hole appears on the right, turn on the first electromagnet 75 to adsorb the long angle steel, and the micro stepper motor 73 drives the adsorption frame 74 to rotate 90° clockwise. The long angle steel at the bottom during the welding process is placed and operated in the same way.

[0058] Place the short angle steel on the right: if the side without the fixing hole appears on the left, turn on the first electromagnet 75 to adsorb the short angle steel, and the micro stepper motor 73 does not operate; if the side without the fixing hole appears on the right, turn on the first electromagnet 75 to adsorb the short angle steel, and the micro stepper motor 73 drives the adsorption frame 74 to rotate 180°, and the short angle steel placed on the left is operated in the same way.

[0059] The dual-axis translation mechanism 8 consists of a transverse translation member 81 and a longitudinal translation member 82. The transverse translation member 81 includes two groups of first support shafts 811 relatively installed on the transverse plate 12 and the vertical plate 11. The first support shaft 811 is sleeved with a first chain 812. A second electromagnet 813 is installed at the end of the micro-stepping motor 73 away from the adsorption frame 74. The second electromagnet 813 is fixedly connected to the first chain 812 through a connecting block. A first motor 814 is installed on the vertical plate 11. A first sprocket 815 is installed on the output shaft of the first motor 814. The first sprocket 815 and the first chain 812 are meshed with each other. A second slide groove 816 is opened on the vertical plate 11. The second slide groove 816 and the first slide groove 71 are in the same straight line and are connected to each other.

[0060] The longitudinal translation member 82 includes a third slide groove 821 opened on the vertical plate 11, the third slide groove 821 is connected to the second slide groove 816 and are perpendicular to each other, a bracket 822 is relatively installed on the vertical plate 11, and the bracket 822 is slidably connected to the second support shaft 823, a connecting rod 824 is arranged between the two second support shafts 823, and both are rotatably connected to the second sprocket 825, the second sprocket 825 is connected through a second chain 826, and a cross bar 827 is relatively installed on the second chain 826, one of the cross bars 827 is installed with an electric control valve 828, a second motor 829 is installed on the vertical plate 11, and a third sprocket 8210 is installed on the second motor 829, and the third sprocket 8210 and the second chain 826 are meshed with each other.

[0061] When the servo motor 6112 drives the angle steel to rotate, the lateral translation member 81 drives the adsorption frame 74 away from the angle steel to avoid motion interference. After the side of the angle steel with the fixing hole is opposite to the plane where the vertical plate 11 is located, the adsorption frame 74 is driven to surround the angle steel, and the angle steel is adsorbed into the adsorption frame 74 through the first electromagnet 75.

[0062] After the adsorption frame 74 adsorbs the angle steel to itself through the first electromagnet 75, the first motor 814 is turned on. The first motor 814 drives the first chain 812 to rotate through the first sprocket 815. The second electromagnet 813 is in the on state by default and is in the adsorption state with the micro stepper motor 73. In this state, the first chain 812 drives the angle steel to move horizontally synchronously through the second electromagnet 813, the micro stepper motor 73 and the adsorption frame 74, which is used to place the horizontal short angle steel. It should be noted that in the process of placing the short angle steel on the right side, the second support shaft 823 will be driven to slide synchronously on the bracket 822 through the second chain 826. After the placement is completed, the electric control valve 828 is opened, and the two cross bars 827 are cooperated to surround the second electromagnet 813. In the process of resetting the second electromagnet 813, the second support shaft 823 and the connecting parts are synchronously driven to reset. After the second support shaft 823 is reset, the electric control valve 828 is opened synchronously.

[0063] When placing the long angle steel, after the second electromagnet 813 moves between the two cross bars 827, the first motor 814 and the second electromagnet 813 stop working, and the second motor 829 is turned on synchronously, and the long angle steel is driven to be placed longitudinally through the third sprocket 8210, the second chain 826, the cross bar 827, the micro stepper motor 73, and the adsorption frame 74.

[0064] The clamping mechanism 9 includes an electric slide rail 91 installed on the vertical plate 11. There are four groups of electric slide rails 91, two of which are located on the upper and lower sides of the second slide groove 816, and the other two are located on the left and right sides of the third slide groove 821. A rotating cylinder 92 is installed in the electric slide rail 91, and a clamping plate 93 is provided on the rotating cylinder 92.

[0065] After the angle steel moves to the corresponding placement point, the rotating cylinder 92 is started, driving the clamping plate 93 to limit the angle steel and fix the position of the angle steel. The setting of the electric slide rail 91 allows the angle steel to be finely corrected, making the fit between the angle steels more compact and improving the quality of welding. This part can also be used in conjunction with the existing visual recognition system to avoid deviations caused by external forces, thereby making timely corrections.

[0066] It should be noted that the opening and closing timing of each part of the electric control components can be achieved through programming, which is a prior art.

[0067] The welding mechanism 10 is a miniature four-gun welding machine.

[0068] The welding mechanism 10 is a robot arm provided with a welding gun.

[0069] Enterprises can choose according to their actual productivity and cost. The micro four-gun welding machine has higher welding efficiency, and the robotic arm equipped with welding guns has lower cost.
